According to the World Health Organization (WHO), around 2.6 billion people
|
|
|
|
|
cook and heat using polluting open fires or simple stoves fuelled by kerosene,
|
|
|
|
|
biomass (wood, animal dung and crop waste) and coal (Air Pollution Data Portal,
|
|
|
|
|
n.d.). This generates high levels of health-damaging Indoor Air Pollution
|
|
|
|
|
(IAP), such as particulates, tar and carbon monoxide. Because women are
|
|
|
|
|
primarily responsible for cooking and raising young children, both are
|
|
|
|
|
disproportionately affected by IAP. For example, the World Health Report (2002)
|
|
|
|
|
states that in developing countries among the poor, Acute Respiratory Infection
|
|
|
|
|
(ARI) is one of the leading causes of childhood mortality (under 5) and is
|
|
|
|
|
responsible for up to 33% of all ARI cases. IAP also adversely affects Zimbabwe
|
|
|
|
|
because of the number of people who live in poor, rural regions. (Rural
|
|
|
|
|
Population (67% of Total Population…2020) - Zimbabwe | Data, n.d.).

|
A second problem caused by open or traditional heaths is the inefficient use of fuel. Past efforts to
|
|
|
|
|
reduce IAP have focused on efficient combustion but have not necessarily focused on thermal efficiency
|
|
|
|
|
of the overall cooking and heating process. As a result, a significant portion of the fuel's energy is lost,
|
|
|
|
|
leading to increased levels of deforestation. In parallel, people who are faced with the challenge of
|
|
|
|
|
indoor air pollution are from low-income communities which makes it very difficult for them to afford
|
|
|
|
|
expensive clean cooking stoves. Most of the existing solution focus only on reduction of Indoor Air
|
|
|
|
|
Pollution, but fall short on distribution the solution to billions of people who need it.

Because of the above issues, the engineering goal of this experiment is to create pattern designs of creating an
|
|
|
|
|
affordable, simple, and efficient cooking system whose design is based on origami. Origami is the Japanese
|
|
|
|
|
technique of creating complex 3-dimensional objects from flat sheets of paper. All that is needed to make a well
|
|
|
|
|
known object such as a Crane, Cube or Lion is the pattern and a piece of paper. Likewise, the clean cooking
|
|
|
|
|
system's components will be fabricated from flat metal sheets using simple folds and cuts, enabling them to be
|
|
|
|
|
made worldwide without complex fabrication techniques. Additionally, if a component;s pattern is known, it can
|
|
|
|
|
produce it using locally available material and tools. This reduces or eliminates funding and production
|
|
|
|
|
bottlenecks that have limited the impact of prior efforts when attempting to produce and distribute billions of
|
|
|
|
|
units worldwide.

|
Since many regions that suffer from indoor air pollution also have electricity shortages, the practicality of using
|
|
|
|
|
the thermoelectric chips to generate electricity from the cooking stove's waste heat is evaluated. Its cost per watt
|
|
|
|
|
hour is compared to alternatives such as simple solar panels with local storage (batteries or super capacitors.)
